Fuel cells

A fuel cell is an electrochemical conversion device. It produces electricity from external supplies of fuel (on the anode side) and oxidant (on the cathode side). Fuel cells are very useful as power sources in remote locations, such as spacecraft, remote weather stations, large parks, rural locations, and in certain military applications. Other applications can include cogeneration for family homes, office buildings and factories. Electric and hybrid vehicles could also use this new technology.
